Big Ideas
- Geometric relationships change depending on the type of geometry (Euclidean vs. spherical).
- Fundamental properties like parallel lines and triangle angle sums are defined differently in different geometric systems.
Essential Questions

- Why does the sum of the angles in a triangle vary between Euclidean and spherical geometry?
- What are the key features that distinguish Euclidean and spherical geometry from each other?
- How does changing the type of geometry affect other geometric relationships and theorems?
- How can you use specific examples to illustrate differences between Euclidean and spherical geometry?
